15、ent (COPM) and the EIHydrocarbon Management Committee (HMC).The COPM and HMC are responsible for the production and maintenance of standards and guides covering variousaspects of static and dynamic measurement of petroleum. The API/EI Joint Committee on Hydrocarbon Management(JCHM), its subcommittee
16、s, and work groups consist of technical specialists representing oil companies, equipmentmanufacturers, service companies, terminal and shipowners and operators. The API/EI JCHM encouragesinternational participation, and when producing publications, its aim is to represent the best consensus of inte
17、rnationaltechnical expertise and good practice. This is the main reason behind the production of joint publications involvingcooperation with experts from both the API and EI.This standard is intended to provide guidelines for measurement and sampling of cargoes on board tank vesselsusing closed and
18、 restricted equipment. However, it is not intended to preclude the use or development of any othertechnologies or methods. To gain a better understanding of the methods described in this standard, the reader shouldreview in detail the latest editions of the publications, standards, and documents ref
19、erenced herein.SI units are used throughout this publication as the primary units of measure because this system is commonly usedin measurement and sampling. However, US Customary (USC) units continue to be used in some applications.Therefore, both SI and USC units are shown (with USC in parentheses
20、).This standard is not intended to supersede any safety or operating practices recommended by organizations such asthe International Maritime Organization (IMO), International Chamber of Shipping (ICS), and Oil CompaniesInternational Marine Forum (OCIMF), or individual operating companies, nor is th
21、e publication intended to supersedeany other safety or environmental considerations, local regulations, or the specific provisions of any contract.All shipboard procedures described in this standard should be performed by or in the presence of the ships master orthe designated representatives. For r
22、easons of safety, only approved equipment certified intrinsically safe orotherwise approved suitable for its intended use shall be used.API/EI standards are published as an aid to procurement of standardized equipment and materials and/or as goodpractice procedures. These standards are not intended
23、to inhibit purchasers or producers from purchasing orproducing products made to specifications other than those of API or EI.Classified areas may vary depending on the location, conditions, equipment, and substances involved in any givensituation. Users of this standard should consult with the appro
24、priate authorities having jurisdiction. Users of thisstandard should not rely exclusively on the information contained in this publication. Sound business, scientific,engineering, and safety judgment should be used in employing the information contained herein.Shall: As used in a standard, “shall” d
25、enotes a minimum requirement in order to conform to the requirement.Should: As used in a standard, “should” denotes a recommendation or that which is advised but not required in orderto conform to the requirement.May: As used in a standard, “may” denotes a course of action permissible within the lim
26、its of a standard.Can: As used in a standard, “can” denotes a statement of possibility or capability.This publication was produced following API/EI standardization procedures that ensure appropriate notification andparticipation in the developmental process and is designated as an API/EI standard.Qu
27、estions concerning the interpretation of the content of this publication or comments and questions concerning the procedures under which this publication was developed should be directed in writing to the Director of Standards, American Petroleum Institute, 1220 L Street, NW, Washington, DC 20005, U
